<script>
	// 1. 使用 ` 符号实现换行
	let str1 = `hello,
es6 demo`;
	console.log(str1);

	console.log("========================");

	// 2、字符串插入变量和表达式。变量名写在 ${} 中，${} 中可以放入 JavaScript 表达式。
	let name = "Mike";
	let age = 27;
	let info = `My Name is ${name},I am ${age + 1} years old next year.`;
	console.log(info);   // My Name is Mike,I am 28 years old next year.

	// 3、字符串中调用函数
	function f() {
		return "have fun!";
	}

	let string2 = `Game start,${f()}`;
	console.log(string2);  // Game start,have fun!
</script>
